Spinor-Vector Duality in Heterotic SUSY Vacua [PDF]
, 2008 We elaborate on the recently discovered spinor-vector duality in realistic free fermionic heterotic vacua. We emphasize the interpretation of the freely-acting orbifolds carried out on the six internal dimensions as coordinate-dependent compactifications;

String Theory - From Physics to Metaphysics [PDF]
, 2006 Currently, string theory represents the only advanced approach to a unification of all interactions, including gravity. In spite of the more than thirty years of its existence it did not make any empirically testable predictions.

The Exact MSSM Spectrum from String Theory [PDF]
, 2005 We show the existence of realistic vacua in string theory whose observable sector has exactly the matter content of the MSSM. This is achieved by compactifying the E_8 x E_8 heterotic superstring on a smooth Calabi-Yau threefold with an SU(4) gauge ...

On Four Dimensional N=1 Type I Compactifications [PDF]
, 1998 We consider four dimensional N=1 supersymmetric Type I compactifications on toroidal orbifolds T^6/G. In particular, we focus on the Type I vacua which are perturbative from the orientifold viewpoint, that is, on the compactifications with well defined ...

, 1995 We present dyonic multi-membrane solutions of the N=2 D=8 supergravity theory that serves as the effective field theory of the $T^2$-compactified type II superstring theory.

Bound States Of Strings And $p$-Branes [PDF]
, 1995 The recent discovery of an explicit conformal field theory description of Type II $p$-branes makes it possible to investigate the existence of bound states of such objects.

Eluding SUSY at every genus on stable closed string vacua [PDF]
, 2011 In closed string vacua, ergodicity of unipotent flows provide a key for relating vacuum stability to the UV behavior of spectra and interactions. Infrared finiteness at all genera in perturbation theory can be rephrased in terms of cancelations involving

Supersymmetry and the Supergravity Landscape [PDF]
, 2006 In the recent times a lot of effort has been devoted to improve our knowledge about the space of string theory vacua (``the landscape'') to find statistical grounds to justify how and why the theory selects its vacuum.

Supersymmetry preserving and breaking degenerate vacua, and radiative moduli stabilization [PDF]
, 2017 We propose a new type of moduli stabilization scenario where the supersymmetric and supersymmetry-breaking minima are degenerate at the leading level. The inclusion of the loop-corrections originating from the matter fields resolves this degeneracy of ...

Supergravity solitons and non-perturbative superstrings [PDF]
, 1995 A review is given of the implications of supersymmetric black holes for the non-perturbative formulation of toroidally compactified superstrings, with particular emphasis on symmetry enhancement at special vacua and S-duality of the heterotic string ...
